Yes.
2. 2 plus 2 equals 4 and 2(2)= 4
They are expressions.
In C++ all false relational expressions have a mathematical value of 0.

five plus five equals ten...
If a + b = 6, what is the value of 3a + 3b?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
2 plus n is the true one, but 1 plus n is not?
The expression "6x plus 9" is written as (6x + 9). The expression "x minus 1" is written as (x - 1). These are two separate algebraic expressions and do not simplify or combine unless you have a specific value for (x). If you provide a value for (x), we can evaluate both expressions.
You meana += ++a - --a?Well, it can be anything, depending on the compiler's decision. Never ever write expressions like this.
The answer depends on the value of y.
